[R-SIG-Mac] Blank help window

[zListserv]

Many thanks for your suggestions.  Not sure whether Ben’s issue is the same as mine.  Ben has problems with ?data.frame.  My issue is a blank help window when typing ?mean (or any other function).

Peter suggested checking capabilities().  They are all TRUE.

You both suggested checking configuration files.  Removing .Rprofile, .Rdata, and .Rapp.history made no difference.

Help works when running R from console

No effect in R (except it opens my default browser).
